To all 1071,0112 it may concern:

Be it known that 1, WILLIAM H. PRUYN, Jr, a citizen of the United States, residing at Chi-- cago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Concrete Railway-Ties, of

which .the following is a specification. I

My'invention relates to railway-ties, and

has for its object to provide new and improved constructions for such ties, and particularly for .thosemade of a composition such as concrete or the like.

My invention is illustrated in. the accompanying drawings, whereirh Figure 1 1s a crosssection through one form of my tie, showing the rail in elevation Fig. 2, an elevation of the tie of Fig. 1 with parts broken away and the rail in section; F ig. 3, a plan view of a different form of tie; Fig. 4, a cross-section of the same; Fi 5, a longitudinal section showing a modifie form of rail-clam ing device; Fig-6, an elevation of another orm of tie; Fig.7, a plan view, with parts broken away, of another modification; Fig. 8, a sectioh online 8 8 of Fig. 7.; Fig. 9, a cross-section through a different form-of tie embodying my invention, and Fi 10 a like view of a modification with the a removed.

Like letters of referenceindicate likeparts in all the drawings.

Mytie consists in general of a body part A, which is preferably composed of some concrete-lik material which may be reinforced in any 0 dinary manner, and of a rail seating part which I prefer to make relatively thin; and of some stronger material or composition; To this seating portion of the tie is clamped or otherwise secured the rail B.' In order to facilitate this end and also to lighten the structure, the tie is channeled beneath the seating part, the latter being preferably embedded in the composition forming the tie, so

preferred sort.

that it acts asa reinforcement to the-structure at that place.

Referring-particularly to Figs, 1 and 2-, the body portion A-of the tie is shown as reinforced bya plurality of longitudinal rods C C, of steel or other material; The reinforcement of the concrete may, however, be of any The tie is here shown as having the channel D on its upper surface and running the length of the tie." I The rail-seat is composed of lthefchannel -iron E, which bridges overthe'iapertiire D, its'flanges E- E being e concrete. Therail Patented Feb. 1a, 1906.

rests upon the upper surface of the part E and may be secured thereto in any desired manner. The channeling of the. tie at D gives easy access to the. lower surface of the part E, so that almost any form of device may be used for securing the rail inposition. I

I have here shown a securing device consisting of the two plates F F, arranged staggered, one on each side of, the rail, and which overlap the lower flangeof the railand are secured to the channel-iron E bymeans of the The chan- 7 bolts F F and the nuts F F nel-iron, it will be seen, therefore forms a bridge over the aperture D, and to this bridge the rail is secured. By being embedded in the cement the'channel-iron strengthens the tie at the place where it is weakened by the channeling. 1

In Figs-3 and 4 I have shown a modified form of tie. The upper surface of the tie is traversed by two longitudinal channels G G, and there is also a similar channel Gton the under side of the tie. In the device of Figs. 1 and 2 the channel-iron E is represented as running the whole length of the tie. That of course is not essential, and in the form shown in Fig. 3 the rail-seat extends onlya short distance each side of the rail. In this form of device I have shown the rail-seat as consist ing of a channel-iron G, provided with flanges G G The rail may be fastened to the part G in any desired manneras, for example, by the plates F F, bolts F F, and nuts F F in the same manner as is shown in Figs. 1 and2. It is not essential, of course, that the bridge to which the rail is clamped should be made of iron or steel, as described. This bridge or rail-seat may, on the contrary, be com osed of the same material as the body of t e tie and made integral therewith. I have shown this construction in Figs. 7 and 8.' The tie has the longitudinal channel H, which is bridged at each end at the place where the rail-rests by a relatively thin concrete structure H, which is built upon or around a metallic netting or other reinforcement H the H H. .The bridge or rail-seat is perforated at H? H by means of which the rail may be clamped thereto in the manner before described. A-somewl-1at different structure,but

IIC

embodying the same'principles, is illustrated in Fig. 9.; I Here thebody of the tie A has lon- 'tudinal 'channels J J on its sides, thus forms arail-seat J, which is erforated for the b ts F b' means of whic the rail may be fastened t ereto, as described. In order to strengthen the relatively thin seating ortion formed b the channels .J J, I embe in cementthe ongitudinal reinforcements J- J extending throu h such seating part and anchored in the ody of the tieln the manner shown. I may also embed inthe cement the. longitudinal rods J 3 J Fig. 10 shows afuif'ther mo two oppositelylaced angle-irons K K, riveted to ether at and embedded in the concret'e-o the tie. The an le-ironsKK are provided with the staggere perforations K K In some instances it is desirable to construct the tie upon which the rail will rest more elastically t an is possible when the pressure is immediately u on the mass of concrete. In Fig. 6 I have s own anarrangement for securing such elastic seating of the rail. The upper surface of the tie' is provided at each en with a transverse channel L which is brid ed by a transversely-placedchannel- -iron -or somelike structure, and upon this is clamped the rail B in any desired manner.

The all port of the rail will therefore be some what el astic. In orderto decrease the weight of the structure, 'thetie may be cut away on the under side, as shown at L In the other figures Ihaveshown the railas bolted to the bridg'e'or rail-seat. The rail, however, may be secured to the tie in any desired manner. In Fig. 5 I have shown .a device which is-particularly adapted to be used M in such rail-seat a the rail. A screw-bolt M, taking into the in connection with the tie of my'invention. It consists of a clam ing device having two parts, one of which, extends under the railseat M therewith and passes u through the aperture overlaps the flange of part M, presses the part M down upon the rail-flange. The form of securing device is of course not an essential art of my invention.

I have described wit some particularity several structures embodying my invention; .but it wil-lbfe understood that there mi ht be other modifications made in details 0 ,form; and constructionwithout departing from the spirit and purpose of my invention. Therefore-I do not wish'to limit myself to the par ticular'forms and devices herein shown, but

desire that the drawings be taken as in asensej diagrammatic and illustrative. of my invention as disclosed in a few of its vanous embodiments.

The use and operation of my invention will perhaps have been made sufficiently clear by secureby constructing my tie in the mannershown a cheap com aratively light tie, to which the rails maye very easily and very permanently secured. The channeling of the" ification in which the rail-seat consists of o and the other, M which is integral the foregoing. It is sufficient to say that I concrete structure decreases its w; a I the same time gives access to the under side of the rail seat. The latter is arranged to reinforce the tie ,at the places where it is weakseating part.
